Installs esbuild under `_build`.
```bash
$ mix esbuild.install
$ mix esbuild.install --if-missing
```
By default, it installs #{Esbuild.latest_version()} but you
can configure it in your config files, such as:
config :esbuild, :version, "#{Esbuild.latest_version()}"
You can pass the `--if-missing` flag to only install it if
one does not yet exist.
